Have you considered submitting a design document to the oVirt website.<br>
We will be happy to help in making this happen.<br>

I believe there is already one here: <a href="http://www.ovirt.org/develop/release-management/features/infra/drbd/" rel="noreferrer" target="_blank">http://www.ovirt.org/develop/release-management/features/infra/drbd/</a><br>

I would be happy to update it as that was written for DRBD 8.4 and I'm working with DRBD 9.<div class="HOEnZb"><div class="h5"><br>

Can you explain the use case? What are you trying to use VDSM for?<br>
The API you want to use is internal and can break without notice.<br>

Hi Yaniv,<br>
<br>
I'm working to to integrate DRBD storage into VDSM.<br>
<br>
It will be a new type of storage domain, so I can't use the GUI since the<br>
engine component won't be aware of it as far as I can tell.<br>
<br>
The current plan is to have another developer on our end make changes to<br>
the<br>
Engine once the VDSM side is working.<br>
<br>

<br>
Hi Hayley,<br>
<br>
Sounds cool, can you describe in more details the use case, and how do<br>
you think this<br>
can work?<br>
<br>
<br>
</blockquote>
Hi Nir,<br>
<br>
The use case is to make replicated block level storage available in oVirt.<br>
<br>
VDSM should be able to communicate with DRBD via DRBD Manage, which is a<br>
new administrative layer for the latest release.<br>
<br>
Cheers,<br>
